Abstract: To solve the single machine scheduling problem with a sequence dependent setup times, a multi-objective optimization model is set up. The object is minimum of the total setup time, the total tardiness and the rate of delay in delivery. An improved adaptive multi-objective harmony search algorithm is proposed. Information entropy is employed to estimate the diversity and crowd degree of individuals in the population. The results of experimentation show that the proposed algorithm is effective and feasible.
